I don't quite remember where I found this link, but this is a great resource for information on coins, paper money, etc. https://nnp.wustl.edu/library/books If you are looking for back additions, older books, and any other numismatic related history this is a one stop shop. And it is free.
Thank you for the link. It looks at first glance as a great resource to learn more about an ever changing hobby!
I have the NNP bookmarked - it has a wealth of information for research that I have gone to quite a few times. Thanks for sharing!
I wish they had a better website (user interface is clunky), but the wealth of knowledge stored here is fantastic. I wish more people knew about it and took advantage of the Newman Numismatic Portal. My understanding is that some of the proceeds from the recent magnificent sale of his collection is helping to fund this effort.
I think the wealth of knowledge overcomes any web site issues. It is likely that the web issues will resolve themselves as the site evolves over time. I don't think I have seen quite that much data in one spot. I thought the one area that needed help was the biographies. Some of these are on living numismatists and they have a chance to write their own biography I think. Unlikely that I will be commemorated, but there are a lot who will.
