I was recently alerted to a new Math Portal, Vlib MATH. Katharina Habermann said Vlib MATH offers access to link-collections, library catalogs, journals, other databases, subject-specific search engines, full-texts, digitized material and more. The search covers electronic as well as printed material.

At the moment the portal is still under construction. There are a lot of ideas and add-ons being planned to widen our service. Developed by mathematicians and librarians, they are very much interested in feedback.

Recently, they launched an english version of the portal. It is available via the URL http://www.vlib-math.de/ .
