+
+(** We've covered quite a bit of ground so far.  Here's a quick review...
+
+   - _Functional programming_:
+          - "declarative" programming style (recursion over immutable
+            data structures, rather than looping over mutable arrays
+            or pointer structures)
+          - higher-order functions
+          - polymorphism *)
+
+(**
+     - _Logic_, the mathematical basis for software engineering:
+
+               logic                        calculus
+        --------------------   ~   ----------------------------
+        software engineering       mechanical/civil engineering
+
+          - inductively defined sets and relations
+          - inductive proofs
+          - proof objects *)
+
+(**
+     - _Rocq_, an industrial-strength proof assistant
+          - functional core language
+          - core tactics
+          - automation
+*)

+(* ################################################################# *)
+(** * Looking Forward *)
+
+(** If what you've seen so far has whetted your interest, you have
+    several choices for further reading in later volumes of the
+    _Software Foundations_ series.  Some of these are intended to be
+    accessible to readers immediately after finishing _Logical
+    Foundations_; others require a few chapters from Volume 2,
+    _Programming Language Foundations_.  The Preface chapter in each
+    volume gives details about prerequisites. *)

+(** * Resources *)
+
+(** Here are some other good places to learn more...
+
+       - This book includes some optional chapters covering topics
+         that you may find useful.  Take a look at the table of contents and the chapter dependency diagram to find
+         them.
+
+       - For questions about Rocq, the [#coq] area of Stack
+         Overflow ({https://stackoverflow.com/questions/tagged/coq})
+         is an excellent community resource.
+
+       - Here are some great books on functional programming
+            - Learn You a Haskell for Great Good, by Miran Lipovaca
+              [Lipovaca 2011] (in Bib.v).
+            - Real World Haskell, by Bryan O'Sullivan, John Goerzen,
+              and Don Stewart [O'Sullivan 2008] (in Bib.v)
+            - ...and many other excellent books on Haskell, OCaml,
+              Scheme, Racket, Scala, F sharp, etc., etc.
+
+       - And some further resources for Rocq:
+           - Certified Programming with Dependent Types, by Adam
+             Chlipala [Chlipala 2013] (in Bib.v).
+           - Interactive Theorem Proving and Program Development:
+             Coq'Art: The Calculus of Inductive Constructions, by Yves
+             Bertot and Pierre Casteran [Bertot 2004] (in Bib.v).
+
+       - If you're interested in real-world applications of formal
+         verification to critical software, see the Postscript chapter
+         of _Programming Language Foundations_.
+
+       - For applications of Rocq in building verified systems, the
+         lectures and course materials for the 2017 DeepSpec Summer
+         School are a great resource.
