Lots of old books scanned online.

Search for vacuum tube design or similar into Google etc...

www.archive.org   will have many books I believe.

Hard to go wrong with good old RDH4,
http://www.tubebooks.org/Books/RDH4.pdf

May be a little on the heavy side if you're more generally beginner, than an 
active designer and just unfamiliar with tubes in particular.

Also plenty of articles and web pages by varying degrees of experts, fans 
and nuts.  Tubecad comes to mind as one of the generally informative ones. 
Downside is, the audioph{ile|ool} community won't give the most practical or 
representative picture of things, so keep that in mind.

An RDH4 alternative from the time period that's a bit more compact but 
covers the important topics:

** Your Q is way too broad - the topic of tubes is ENORMOUS while current production involves only a few popular audio types. 

FFS tell us what you ACTUALLY wish to know about.

I totally agree with Tim's recommendation including the caveats.

RDH4, in case you haven't already found out, stands for Radiotron 
Designer's Handbook 4th Edison. It was my bible in the early 
days. I still have the original print as well as the pdf.

There are loads & loads to choose from. Most of them contain all the basic info. I see no point limiting yourself to one or 2 possibles, see what you can find.

I thought this one useful enough to republish in 
electronic format.

A search for 'Conductance Curve Design Manual' should 
get a pdf version.

Dunno exactly what you're looking for, but the suggestions you've gotten so far are for books about designing *with* valves/tubes.  Another dimension is the design *of* valves/tubes.  If that's what interests you, look up "1940 RCA Vacuum Tube Design." (There are also later editions.) You can find free PDFs on the web.  I find the subject fascinating (and who knows, it may be relevant again in a post-apocalyptic world :-) )
