glean from bibliographic sources to complete the request. The more information you give us the more likely we are to locate the material you need—and the more quickly.

Try to develop techniques for drawing from your reader as much as he knows about the item he is seeking and the source of the citation. He must have some reason for believing the item exists, and we should be able to pass this information on to the potential lending library.

Verification

Check as far as possible to verify the accuracy of the information the reader gives you. We trust that you will verify citations as completely and as accurately as your resources will allow.

The ALA and NYSILL manuals (see Appendix A) both contain a listing of standard bibliographic tools and sources of verification. Verification sources not found in the standard lists should be cited in full. Remember that reference tools and abbreviations familiar to you may not be known to the librarian trying to fill the request. Please give full citation of the source of verification, including date, volume, series, and the page on which verification was found. That is, not just "NUC," but "NUC, 1968-72, 25:478." In a request for a periodical article, both the title of the periodical and the location of the article should be verified, and both sources of verification should be given.

If you cannot verify the item in a standard bibliographic tool, please supply a complete citation to the source of reference, including author's full name, publisher, date, and page of citation.

When libraries are unable to verify requests completely because their bibliographic resources and staff are severely limited, we will try to verify the information and to locate the item. If a request is hopelessly inadequate, with vital information missing or with incomprehensible abbreviations, we will return it for clarification.

OCLC verification

Please use caution when citing OCLC numbers as verification for interlibrary loan requests. The Council office and most of the libraries in our region do not have OCLC terminals. Include OCLC #, author and title, place, publisher and date, and Nassau-Suffolk and NYSILL locations where given. Be sure all information has been copied correctly.

Data base verification

If an item is requested on the basis of a citation on a computer printout, supply all information given and be sure to indicate which data base was used, such as ERIC, Psych Abstracts, Compendex, BIOSIS, etc.

Photocopying

The lending library may choose to supply photocopies of articles in lieu of lending whole issues or volumes of serials. By mutual agreement, libraries in our region generally absorb the costs of photocopying articles, although there may be a charge for longer articles. Libraries have usually found that by photocopying for each other without charge they come out reasonably even and avoid the expense and trouble of accounting and billing procedures.

Expenses

LILRC along among the 3R's Councils in the State has chosen to maintain a low membership fee which is the same for all libraries. Our income is supplemented by a system of charges and credits for completed interlibrary loan transactions, so that libraries pay in proportion to the use they make of our service. These charges are not related to the cost of the service.

The borrowing library is charged a fee for each item it obtains through LILRC. The lending library receives a credit (presently $1.00) equal to one-half the charge (presently $2.00) for each item it supplies. Libraries with collections from which we borrow heavily, paying for teletype machines to receive our requests, may be given
