This used to be the go-to source for statistics before the days of Google. While I'm sad to see it go, in the current age, the Abstract while useful for pointing to the data source of the table is a product of the pre-Internet era. We use to put together time series by hand from various editions of the Abstract and today this is no longer necessary. Nor is it necessary to publish this as a hardbound book. I'd like to Census use this opportunity to re-launch the information on the Internet in a more interactive form.
The strength of the Abstract was in its summarized form e.g. by state and a snap-shot for various years. While it would be infeasible to pull all the information together from scratch, it would be great to at least link all the tables to the main data sources and if possible for the user to generate additional time points that are not shown or to re-summarize the data at a different level.
