Around that time, about 150 libraries sent staff to NLM for three weeks or more of training. Altogether, they performed a few thousand searches a year. Since then, things have definitely improved. Now all NLM databases are available free on the Web.
Heaviest use is still from health professionals and researchers.
This translates into approximately two million PubMed searches each month performed by librarians. We receive electronic data for about 450 journals including some from nearly all major publishers. This will continue to grow and it will mean more links to publisher Web sites. These thousands of additional records are retrievable in author and text word searches and will be have the Related Article feature. About six months ago, NLM implemented a system enhancement that dramatically increased the speed of PubMed.
