Alpes Vaudoises et Valaisannes: itinéraires d'altitude
Author(s): F. Weill
Publisher, year: Franck Randonnée, 1996. Probably out of print and very hard to find.

A very original selection of hikes: many routes are not on main trails, lead to less known passes or to summits which can be reached by experienced hikers. Almost all the hikes culminate at around 3000m and often go even higher. Some require alpine equipment or climbing skills, some others are off-trail, but on the whole, the guide is mostly about hiking. Each route is covered in great detail and with the help of very accurate hand made sketches.

[Updated 1-Aug-2012: A new edition of this book, under the title Les neiges et rocs du randonneur has appeared in 2008. I could buy a copy and list it under #89 of this bibliography]

Clubhütten, Cabanes, Capanne, Huts
Author(s): -
Publisher, year: Swiss Alpine Club (SAC), 1987

Multilingual.
The official hut index. For each of them, the guide provides the following informations: small black and white picture, duration of ascent, caretaking periods, elevation, map coordinates, number of beds, phone number,... and other practical details. Unfortunately, very few words on the route.
All texts are written in 4 languages.
This is an older edition with probably outdated data. I recommend the #21 instead, which I think is the new edition of that same guide.

Das grosse Clubhüttenbuch, Le grand livre des cabanes, Il gran libro delle capanne
Author(s): W. Furter
Publisher, year: Orell Füssli, year not given

Multilingual.
Roughly the same content as the previous book (#2), only with bigger color pictures and in a less practical size.

Randonnées en altitude
Author(s): P. Metzker
Publisher, year: Swiss Alpine Club (SAC), 1986

Fairly detailed routes, some are reserved for alpine climbers, some others are longer excursions which last several days. Includes diagrams of time and elevation gain/loss.
The book covers all regions of Switzerland. I find a more recent book from the same author fits my needs better, since it focuses on the French speaking part of the Swiss Alps: it is the #14, Randonnées alpines - Suisse romande.

Available translated in English at Amazon.co.uk and Amazon.com, translated in French at Amazon.fr or in the original German version at Amazon.de.

Excellent small guide from the Rother collection. I like its handy size, the map extract and the picture given for each of the 50 trips. The selection ranges from easy but interesting strolls at lower altitudes to alpine hikes. On the whole, I consider it to be a very good choice for experienced hikers who seek enjoyment rather than performance. It's my second favourite guide, after the #1.
Several Rother pocket books have been translated into French or English. Please check with your librarian or with the publisher's website for availability in your language.

Still from the same collection, and still the same judgement, although the authors for Berner Oberland and Valais are different. This volume handles the Eastern Berner Oberland, where the peaks like Eiger and Jungfrau can be found. Regions included: Grindelwald, lake of Brienz, Grimsel pass, Susten pass.

Valais: randonnées circulaires sous le signe des 13 étoiles
Author(s): Christian Fux
Publisher, year: Kümmerly+Frey, 1994

A book that I haven't used much. The good thing is that, as indicated by the title, all routes are roundtrips and thus possibly more interesting than up and down routes.
This book is certainly available in German too.

Another very good booklet from the Rother collection. Like #7, except it handles the Western part of the Berner Alps (Gstaad, Kandersteg, Lenk, lake of Thun).

Lonely Planet Walking Guide: Walking in Switzerland
Author(s): Clem Lindenmayer
Publisher, year: Lonely Planet, 1996. Second revised edition dates 2001

Available in English at Amazon.com, Amazon.co.uk, Amazon.fr and Amazon.de.

For me personnally, this guide has not been helpful. Its biggest drawback is to deal with whole Switzerland, and so it has dozens of pages on far away regions like Graubünden or the Northwest where I never go (correction: actually, since 2006 I've begun visiting these regions).
On top of that, the described routes often start from a point and end at a totally different point, which is fairly inconvenient for me since it raises an organisation problem. For these reasons, I'd rather recommend the book to tourists who hike through Switzerland using public transportation.
