. However, some Appendix C material should be maintained for historical reasons. These decisions are made by the Federal Documents Librarian. The shelf list and/or bibliographic record is appropriately marked.
Retrospective Collection:
Microform collections are purchased to build the library's retrospective collection of both
depository and Non Depository documents. To this end we have already own the CIS U.S. Executive Branch Documents, 1789 1909 and have purchased the second segment covering 1910 to 1933. We also have the CIS collections of unpublished hearings for both Houses of Congress and continue to purchase supplements. We have purchased the CIS collection of published hearings covering 1833 1944 and will be buying additional segments in the future. We have also purchased the CIS U.S. Committee Prints Microfiche Collection.
Non Depository Material:
The Library collects non depository materials extensively in both paper and microfiche.
1. NTIS. A comprehensive subscription is currently maintained to all regularly priced microfiche reports processed by NTIS (PB reports), Energy Department (DE reports), and the Defense Department (AD reports). We began to comprehensively collect technical reports in 1963.
2. Commercial publishers. Microfiche collections are purchased for unpublished and retrospective material. The Readex Non Depository collection was purchased through mid 1974 when it was cut for budgetary reasons. Since it is based on the Monthly Catalog it does not currently provide enough material to justify its price. The Non Depository fiche collections for ASI, National Security Council Documents, Declassified Documents, NCJRS and other such collections are purchased.
3. National Archives. The microfilm publications from the National Archives are not depository
materials and should be purchased as needed. These were collected heavily in the past but were cut back in the late sixties. Commercial microfilm versions of National Archives collections can be purchased if the National Archives has not already filmed. These purchases should be done very carefully as not all commercial publishers are equal.
4. Documents Expediting Project (DocEx). A full subscription to DocEx services is maintained.
This gives us the automatic distribution materials and allows special orders. DocEx is very good at acquiring non depository material and DND items (depository not distributed). Also, DocEx is extremely useful for replacing missing documents, especially periodical issues, and obtaining
additional copies of depository publications.
5. Congressional Research Service. The complete microform collection Major Studies and Issue
Briefs of the Congressional Research Service has been purchased and a current subscription is
maintained. CRS publications can be requested in paper through the local Senatorial offices and the office of the Second Congressional District.
6. Reviewing the indexes for ASI and NTIS can identify non depository material for
which a paper copy may be more appropriate and depository material which have not been
distributed to depositories. These can be requested from DocEx or purchased if need requires.
7. Agency distribution. Agreements with agencies to automatically receive significant non depository collections should be pursued. The arrangement for the National Park Service to send us their microfiche collections is an example. The Energy Information Administrations sends us all of the EIA publications in paper.
8. Agency web sites can also be used to identify non-depository documents.
Electronic Resources:
Resources from commercial publishers in electronic format are purchased to supplement the depository collection. Bibliographic databases are important. Statistical data files distributed with user friendly software should also be considered. Non Depository CD ROMs and disk products are periodically reviewed for acquisition. Services like the LexisNexis Congressional and the LexisNexis Statistical offering electronic full text and value added indexing should be strongly considered.
Maintenance of Collection:
All discard lists from Colorado and Wyoming Depositories are checked against the shelf. Requests are made for anything not on the shelf. This may occasionally mean that we acquire a second copy of items that were circulating when the list was checked but this is not seen as a problem. Discard lists from out of state and the GPO Needs and Offers List will be checked as staff time allows.
Documents identified as missing or lost by the Circulation Department or by department staff
should be requested from DocEx. Should DocEx not be able to supply the requested items, orders may be placed using the lost book fund.
Claims for depository materials that are returned marked exhausted should be sent to DocEx.
Environmental Impact Statements:
Paper copies of environmental impact statements for Colorado and the surrounding region are obtained for the collection. Others may be added selectively, depending on the topic. The Federal Register is regularly reviewed to identify new EIS.
