Nanosystems (1992) written by Eric K. Drexler - It covers the basics of atomically precise maufacturing and adheres to exploratory engineering to make reliable predictions about future technology

Nanosystems: Molecular Machinery, Manufacturing, and Computation - by K. Eric Drexler

"Nanosystems" ^[1] is the main technical reference book for feasibility analysis of the far term target of atomically precise manufacturing
which is Gemstone based metamaterial technology.

The book is for the most part:

• an identification of a sensible far term target technology
• a stringently conducted feasibility study of this target technology

Only the very last chapter touches briefly and incompletely on eventual approaches that could be part of some pathways towards that target technology.

Only resource

Till day of last review of this text (2023) there is still no other book available that:

• is covering the same topic and
• is also stringently applying exploratory engineering

As the first and last book of its kind it leaves a huge amount of exploratory engineering work that needs to be done.
And as a book that does not focus on pathways it leaves even more there..

Things to note

In the technical book Nanosystems "universal molecular assemblers" are neither proposed nor even mentioned!

Instead in the brief section about pathways at the end of the book the incremental pathway to "nanofactories" is discussed prominently.
Using biotech to get away from biotech ASAP.
The only topic in the book that may be somewhat related to universal molecular assemblers and their direct path context
is a discussion of pressure driven diamondoid actuators and from withing expandable modular plate or block vacuum sealing methods.

Why is this important?
In the preceding popular science book Engines of Creaton "universal molecular assemblers" where discussed. See: Molecular assembler.
This lead to some hype, fear, and negative influence on relevant funding. As discussed in the newest popular science book on the topic: Radical Abundance.
Molecular assemblers are absent from nanosystems not for political reasons but for technical reasons.
One point of evidence being that the dissertation and book was published well before the problems manifested around 2000.

This wiki is written independently by third party and thus
does not necessarily accurately describe the ideas of the author of Nanosystems.

Eric Drexlers 1991 MIT dissertation is as he wrote
"a draft of Nanosystems" and was published by him for free to read.
Unfortunately his website is completely gone now (as of 2021-03). Still available via internet archive (link below).

Note that some parts are missing in the dissertation compared to the book including (not an exhaustive list):
