+## Julia collections
+
+By defining five functions on your citable collection, you can make them interoperate with dozens of generic Julia functions for working with collections of data.
+
+
+## What you need to define
+
+Thes are the five functions you want to define:
+
+```@example bigfive
+using Base.Iterators
+import Base: length
+import Base: eltype
+import Base: iterate
+import Base: filter
+import Base.Iterators: reverse
+```
+
+In many cases, you can implement these functions with a single line of code.
+
+- `length`: return the number of items in your collection
+- `eltype`: return the type of object your collection contains
+- `iterate`: you need to implement two required methods, one for an initial state and taking a single parameter for the collection, a second with two parameters, giving the collection and some state information.  If your collection is indexed (e.g., an Array type), your state information might simply be an index value.
+- `filter`: you can use `collect` to create an Array on your citable collection and filter the resulting Array.
+- `reverse`: similarly, just collect the values of your collection and pass that to `reverse`
+
+
+
+
+##  What you get
+
+
+Some of the functions this gives you are:
+
+*functions returning iterators*:
+
+- `collect`
+- `drop`
+- `dropwhile`
+- `enumerate`
+- `flatten`
+- `partition`
+- `product`
+- `rest`
+- `take`
+- `takewhile`
+- `zip`
+
+*functions returning other kinds of value*:
+
+
+- `accumulate`
+- `all`
+- `allunique`
+- `any`
+- `argmax`
+- `argmin`
+- `collect`
+- `count`
+- `extrema`
+- `first`
+- `in`
+- `isempty`
+- `map`
+- `reduce`
+- `foldl`
+- `foldr`
+- `maximum`
+- `map`
+- `mapfoldl`
+- `mapfoldr`
+- `mapreduce`
+- `minimum`
+- `prod`
+- `unique`
+- `∌`
