The erliest and most basic are the tsearch(), bsearch(), lsearch(), hsearch(), qsort() family:
Man Page for tsearch (linux Section 3) - The UNIX and Linux Forums

C++ Standard Template libs has many very basic containers (no hash):
STL Containers - C++ Reference
map - C++ Reference

To get the hash, many of my employers have had roguewave h++ libraries: RWTPtrHashTable<T>

Don't overlook the fine container objects in JAVA, like tree map:
TreeMap (Java Platform SE 6)

Google reveals a myriad of open source containers/lists/maps/trees/tables. Some RDBMS implement a multi-column index as containers of containers of containers, so each column can be looked up even if others are not there (so the whole container is iterated). Many good wiki on the high level concepts of hash and such, very good to know first, so API controls make sense.

Finally, awk and bash have associative arrays or lookup vectors, which are hash maps (learn the lingo or get out). Just be careful you are not in the simple "array addressed by integer" tutorial! I am sure PERL has all this, too, so read the wiki and pick your poison. Do you grasp the array, linked list (sorted and unsorted), tree and hash basic concepts?

URI::URL(3)						User Contributed Perl Documentation					       URI::URL(3)

NAME
URI::URL - Uniform Resource Locators SYNOPSIS
$u1 = URI::URL->new($str, $base); $u2 = $u1->abs; DESCRIPTION
This module is provided for backwards compatibility with modules that depend on the interface provided by the "URI::URL" class that used to be distributed with the libwww-perl library. The following differences compared to the "URI" class interface exist: o The URI::URL module exports the url() function as an alternate constructor interface. o The constructor takes an optional $base argument. The "URI::URL" class is a subclasses of "URI::WithBase". o The URI::URL->newlocal class method is the same as URI::file->new_abs o URI::URL::strict(1) o $url->print_on method o $url->crack method o $url->full_path; same as ($uri->abs_path || "/") o $url->netloc; same as $uri->authority o $url->epath, $url->equery; same as $uri->path, $uri->query o $url->path and $url->query pass unescaped strings. o $url->path_components; same as $uri->path_segments (if you don't consider path segment parameters). o $url->params and $url->eparams methods. o $url->base method. See URI::WithBase. o $url->abs and $url->rel have an optional $base argument. See URI::WithBase. o $url->frag; same as $uri->fragment o $url->keywords; same as $uri->query_keywords; o $url->localpath with friends map to $uri->file o $url->address and $url->encoded822addr; same as $uri->to for mailto URI. o $url->groupart method for news URI. o $url->article; same as $uri->message SEE ALSO
