My company is currently working with the Welding Research Council Bulletin as it undergoes a major overhaul. When it first started way-back-when, there were often several articles per issue, which came out on a schedule and had subscriptions. Nowadays there is generally one report per issue that comes out randomly, is priced individually and subscriptions have been eliminated (except for those still needing to be filled). Issues usually range ~$100 - $200 and up and the Welding Research Council relies on this revenue to function. It currently has both ISSNs and ISBNs. I see that some institutions have it listed under periodicals, while others have it listed as a book with call numbers, and at others it appears to be noncirculating. We are concerned about an unsuspecting library worker copying an entire issue for interlibrary loan, since for some older issues, one could legitimately copy an article from an issue, while for newer and future issues, a request for a copy would mean copying the entire thing, much like copying an entire book, which could surely be confusing for a workstudy student (and others). Is there something we could do to remedy this? Would it be helpful to eliminate the ISSN? Thanks in advance for any advice or recommendations.
