Information for LibrariesLicense and copyrightThere is no license agreement required for the NBER online service, however the working papers themselves are protected by copyright. Working papers on the NBER web site are copyright by the author(s), not by the NBER itself. Users may download, view and print papers for their personal use, or to give to their colleagues or students, to place in a the subscriber's library collection, or in a university vended or sponsored course pak, or for other fair use appropriate for discussion papers. Short extracts, not exceeding two paragraphs, may be quoted provided clear attribution is given. Subscribers may download any or all papers for archival storage, with subsequent use constrained to fair use as noted above during the subscription term and thereafter. Requests for permissions beyond fair use should be made to the author(s). Current author addresses can often be obtained at http://www.nber.org/people.html. Abstracts may be copied into printed or electronic bibliographic aids without special permission, provided clear attribution is given. Students and employees of the subscriber site may access the NBER web site via proxy or other devices under subscriber control, regardless of the user's actual physical location. Subscribers have access to all the papers on the web site for the duration of their subscription, and may retain copies of papers acquired during the term of their subscription after that subscription lapses, with no obligation to erase or destroy anything merely because the subscription has expired. ArchivesThere is no present plan to remove papers from the web site on the basis of age, however from time to time papers have been replaced or removed at the request of authors. Any subscriber storing papers for later retrieval should have a mechanism in place for detecting revisions so that readers are provided with current versions. Robots and Screen-ScrapersThe following are the only interfaces suggested for robotic access to the working papers: where C is one of W, T, or H and NNNN is a 4 or 5 digit working paper number. Any user implementing a robotic access mechanism is requested to discuss it's action with me. These URLs may also be used for links from reading lists to particular papers. From time to time individual paper requests may be satisfied with temporary links. Please do not incorporate temporary links into long-lived pages, use the interface described here instead. Libraries wishing to place links to our site in their online access systems may use the URLs above, and also where the latter two links point directly to our search engine. Note that since our search engine is freely available, "federated search" vendors do not need special permission to access our site. CatalogingWe understand that the working paper series has been assigned the ISSN 1073-2489. Abstracts and other bibliographic information may be copied into printed or electronic bibliographic aids without special permission, provided clear attribution is given. A machine readable version of our bibliographic database (including the text of abstracts) is available in RePEc format at http://www.nber.org/RePEc/nbr/. Documentation for that format is available at http://ideas.repec.org/stepbystep.html. Virtually all economics working papers from all institutions world-wide are available in that format. You are free to incorporate information from the database into your online bibliographic system. There is an RIS format bibliography appropriate for Endnote at wwpinfo/all_nber_working_papers.ris Google Scholar's format: http://www.nber.org/cgi-bin/googleXMLs.pl?start=w13100&total=100 gives an XML file with bibliographic information for 100 working papers beginning with w13100. This is currently experimental. It takes about 30 seconds per hundred entries, so this isn't a practical way to get a complete bibliography. Or you can get the whole series via:
http://www.nber.org/wwpinfo/googleXML_h.xml
(Historical papers: ~150k) See the XML header for any of these pages for more information on the NLM Journal standard which Google Scholar prefers. MARCA MARC record for any working paper is available at: http://www.nber.org/wwpinfo/marc/all_nber_working_papers.marc sorted in reverse order of publication date. Also, recently published working papers are available in monthly files in the directory http://www.nber.org/wwpinfo/marc/ However, subject headings are JEL rather than Library of Congress. We are interested in following up suggestions for obtaining LCSHs.

Use Attributes
If you use a bibliographic service that needs cooperation from our server to function correctly, please send us information about what our server needs to do. We are quite interested in supporting such functions, but need to be supplied with detailed specifications for the URLs we are expected to respond to. Authorization and LimitsWe authorize subscribers by IP address range and/or domain name. Details are at "Why I may need your network number". For single subscribers login/password authorization is available, however we never provide that in addition to address or domain name authorization. A backstop technology using email address allows all users with email addresses in the subscribers domain to recieve full text, regardless of their network location. Electronic reserve rooms serving large courses are especially encouraged to cache copies of the papers themselves, rather than merely linking to our site. This will avoid overloading our server and your Internet link. A limit of 3 simultaneous downloads to any one IP address is enforced to limit damage from out-of-control robots. Note that the limit is applied per IP address, not per subscription, so that it should not affect subscribers under normal circumstances. If this is a problem for your site because it uses a proxy server or non-transparent firewall please contact me and we will make special provision. Library logos and download statisticsIf you wish the library logo to be displayed on the bibliographic page (so that your users are aware that the library is paying for their access) please send subs@nber.org a URL for the logo and we will add it to bibliographic pages served to your site. A gif file 80 pixels wide by 15-20 pixels high is most appropriate but the browser will accomodate any reasonable size. This logo will be incorporated by reference, and will load from your site each time one of your users is shown an abstract. The series "NBER Working Papers" incorporates the separately numbered series "Development of the American Economy" and "NBER Technical Working Papers" in our search facility and for purposes of serials cataloging. A page with your subscriber information (company name, contact, expiration date, etc) is always available at http://www.nber.org/subscriber_info.pl. This page is dynamically generated depending upon the IP address of of the requesting site. Statistical usage information can be added to that page if you email a request to me. Contact informationI am always available to discuss technical aspects of authentication.
