Accounting Policies [Abstract]
Basis of Accounting, Policy [Policy Text Block]	Basis of Presentation The accompanying unaudited, interim, Consolidated Financial Statements included herein have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission for quarterly reports. In the opinion of management, these financial statements contain all adjustments (consisting of only normal recurring items) necessary to present fairly the financial position of Lee Enterprises, Incorporated and subsidiaries (the “Company”) as of June 30, 2019 and our results of operations and cash flows for the periods presented. The Consolidated Financial Statements should be read in conjunction with the Consolidated Financial Statements and Notes thereto included in the Company's 2018 Annual Report on Form 10 -K. Because of seasonal and other factors, the results of operations for the 13 weeks and 39 weeks ended June 30, 2019 are not necessarily indicative of the results to be expected for the full year. References to “we”, “our”, “us” and the like throughout the Consolidated Financial Statements refer to the Company. References to “2019”, “2018” and the like refer to the fiscal years ended the last Sunday in September. The Consolidated Financial Statements include our accounts and those of our subsidiaries, all of which are wholly-owned, except for our 82.5% interest in INN Partners, L.C. ("TownNews.com"), 50% interest in TNI Partners (“TNI”) and 50% interest in Madison Newspapers, Inc. (“MNI”). Investments in TNI and MNI are accounted for using the equity method and are reported at cost, plus our share of undistributed earnings since acquisition less, for TNI, amortization of intangible assets. On June 26, 2018, we entered into an agreement with BH Media Group, Inc. ("BH Media") to manage Berkshire Hathaway's newspaper and digital operations in 30 markets (the "Management Agreement"). The Company operates BH Media consistent with how it manages its own newspaper and digital operations. Among other decisions, Berkshire Hathaway is responsible for approving operating and capital budgets. The Management Agreement extends for a term of five years and may be extended thereafter for successive one -year terms on such terms as may be mutually agreed to by the Company and Berkshire Hathaway. The Company is paid a fixed annual fee of $5 million, payable quarterly in arrears, and a variable fee based on the financial performance of BH Media. The variable fees are payable annually in arrears. As of June 30, 2019, the end of the first year of the management agreement, we earned fees of $ 11,320,000 .
Use of Estimates, Policy [Policy Text Block]	Use of Estimates The preparation of the Consolidated Financial Statements in conformity with Generally Accepted Accounting Principles ("GAAP") requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenue and expenses, and related disclosure of contingent assets and liabilities. We evaluate these estimates and judgments on an ongoing basis. We base our estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.
New Accounting Pronouncements, Policy [Policy Text Block]	New accounting pronouncements Between 2014 and 2017, the FASB issued several new standards related to revenue recognition ("the New Revenue Standard"). The New Revenue Standard supersedes existing revenue recognition requirements and is effective in fiscal years beginning after December 15, 2017. The New Revenue Standard provides a five -step model in determining when and how revenue is recognized and requires revenue recognition to depict the transfer of promised goods or services to customers in an amount that reflects the consideration a company expects to receive in exchange for those goods or services. The New Revenue Standard also requires new disclosures about the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. We adopted the New Revenue Standard on October 1, 2018, using the modified retrospective method applied to those contracts which were not completed as of that date. We completed our assessment and did not identify any significant changes to our revenue recognition policies. We identified similar performance obligations under the New Revenue Standard as compared with the deliverables and separate units of accounting previously identified under existing guidance. As a result, the timing and amount of our revenue recognition were not impacted and we did not make any adjustments under the modified retrospective adoption method. We have also assessed the new accounting principles related to the deferral and amortization of contract acquisition costs and due to the short-term nature of such costs, we will utilize the practical expedient to continue to expense these costs as incurred. See Note 2 for more information on our revenues and the application of the New Revenue Standard. In August 2016, the FASB issued a new standard to conform the presentation in the statement of cash flows for certain transactions, including cash distributions from equity method investments, among others. There was no change to the Consolidated Statements of Cash Flows as a result of the adoption of this standard for the quarter ended December 30, 2018. Specifically, distributions received from equity method investees continue to be presented on the Consolidated Statements of Cash Flows utilizing the cumulative earnings approach. In March 2017, the FASB issued a new standard to improve the presentation of pension and postretirement benefit expense. As a result of the new standard the service cost component of pension and postretirement benefits expense is recognized as compensation expense, while the remaining components of the expense (benefit) are presented as non-operating income in other, net. This new standard was adopted for the quarter ended December 30, 2018 and has been retrospectively applied to the Consolidated Statements of Operations and Comprehensive Income for all comparative periods presented. We recorded benefits of $ 712,000 and $ 2,135,000 in other, net in non-operating income (expense) for the 13 and the 39 weeks ended June 30, 2019 , respectively. We reclassified benefits of $ 708,000 and $ 2,123,000 from compensation to other, net in non-operating income (expense) for the 13 weeks and the 39 weeks ended June 24, 2018 , respectively. In February 2018, the FASB issued new guidance to allow a reclassification from accumulated other comprehensive loss (“AOCL”) to retained earnings for stranded tax effects resulting from what is commonly referred to as the Tax Cuts and Jobs Act (the "2017 Tax Act"). In the first quarter of fiscal year 2018, we remeasured our deferred taxes related to unrealized gains on our investment balances using the reduced tax rate. As required by GAAP, we recognized the net tax benefit in the provision for income taxes in our consolidated operations statements, and we reclassified a $3,067,000 net tax benefit from AOCL to retained earnings in our Consolidated Balance Sheets. Adoption of the standard had no impact to our Consolidated Statements of Operations and Comprehensive Income or Cash Flows. In February 2016, the FASB issued a new standard for the accounting treatment of leases. The new standard is based on the principle that entities should recognize assets and liabilities arising from leases. The new standard does not significantly change the lessees’ recognition, measurement and presentation of expenses and cash flows from the previous accounting standard. Leases are classified as finance or operating. The new standard's primary change is the requirement for entities to recognize a lease liability for payments and a right of use asset representing the right to use the leased asset during the term on most operating lease arrangements. Lessees are permitted to make an accounting policy election to not recognize the asset and liability for leases with a term of twelve months or less. In addition, the new standard expands the disclosure requirements of lease arrangements. Lessees have the option to use a modified retrospective transition approach, which includes a number of practical expedients. In July 2018, the FASB issued a new standard which provides for an optional transition method that allows issuers to initially apply the new lease standard to all leases that exist as of the adoption date, with the cumulative effect of initially applying the new lease standard recognized as an adjustment to retained earnings as of the adoption date. We intend to adopt the optional transition method on September 30, 2019, the first calendar day of fiscal year 2020. To date we have made progress in our assessment of the new lease standard. Specifically, we have identified the population of leases and key financial metrics associated with each lease for scoping purposes. Additionally, we have selected a software solution that is compatible with our current financial reporting and control environment. Implementation of the software solution and reporting capabilities will occur during the fourth quarter of fiscal year 2019. Based on our progress to date, we anticipate adopting the standard will have a material impact on our Consolidated Balance Sheets as a result of the recognition of the corresponding lease assets and liabilities. However, we do not believe the adoption will have a material impact on our Consolidated Statements of Income or Consolidated Statements of Cash Flows.
